Console Redirection
2-10 MP-RAS Remote Support
Video Display
A screen is not painted/repainted at the remote terminal until the local video
console is updated. Therefore, when you first connect a remote terminal to the
local server, nothing may display at the remote site. This is because no video
changes have occurred since the last screen was output to the COM port.
If you connect to the local server and no video information displays at the
remote terminal, press the Enter key to generate a change to the local screen.
This should trigger the output of the video buffer to the local terminal.
Note: DOS-based applications should be tested to verify BIOS redirection
support since this support relies on BIOS video and keyboard services in order
to operate.
Console Redirection Limitations
Following are some console redirection limitations:
•
BIOS console redirection does not transmit bitmap graphics (such as the
server logo screen that displays before the SCU is invoked); only
character-based data are transmitted. Therefore, a blank screen (or gray
screen in PROCOMM) may display on the remote terminal. Press Enter
to continue.
•
When the server reboots, there is no output from the COM port until the
POST sequence initializes this port. This process may take some time if a
large amount of memory must be tested. The remote terminal screen
continues to display the last contents of the video buffer before the system
reboot until BIOS POST initializes the COM port.
•
To reboot the server remotely, you must either enter the init command
from UNIX or select the reboot option provided on the Diagnostic
Partition and Platform CD-ROM menus, and in the SCU, BIOS Flash,
and Diagnostics Utilities. (If you enter Alt+Delete at a remote
terminal, only the remote terminal is rebooted.)
•
You cannot execute the DOS edit.exe program remotely because the
program uses Alt + keystrokes in its menu code. Use other DOS utilities,
such as the type command, to view text files.
